The first NASA sign at launch pad 39A encouraging the next launch of space shuttle Endeavour at Kennedy Space Center was misspelled and noticed by someone looking at the craft.

When the shuttle rolled out from the Vehicle Assembly Building Wednesday, a giant “Go Endeavour” sign was put on a fence in front of the craft.

However, one item was missing from the sign: the “u” in Endeavour.

Someone spotted the mistake and called KSC to fix it, WKMG-TV reported.

NASA scrambled someone out to pad 39A with a new sign that has orbiter Endeavour’s name spelled correctly.

A photo with the correct spelling was also posted on the Kennedy Space Center’s Web site.

The orbiter is named after HM Bark Endeavour, the ship commanded by 18th century explorer James Cook; the name also honored Endeavour, the Command Module of Apollo 15. This is why the name is spelled in the British English manner, according to Answers.com.
